2. A patient is sitting slightly forward bracing his arms on his knees in a tripod position. This position is associated with which symptom?
a. Abdominal pain
b. Spinal deformity
c. Back pain
d. Breathing difficulty
ANS: D

Feedback
A Positions used by patients with abdominal pain vary depending upon what organ is involved. For example, patients with appendicitis tend to lie very still; those with acute pancreatitis prefer the fetal position for pain relief.
B Spinal deformity usually affects the patients gait or causes a slumped posture.
C Back pain usually affects the patients gait or causes a slumped posture.
D Breathing difficulty is associated with the tripod position, which allows maximal expansion of the muscles of respiration.

6. The nurse suspects an irregularity in the rhythm of the patients radial pulse. What is the most appropriate action for this nurse to take at this time?
a. Document this rhythm as normal for the patient.
b. Use a Doppler to check the brachial pulse.
c. Count the patients apical pulse for a full minute.
d. Count the radial pulse again for 15 seconds and multiply by 4.
ANS: C

Feedback
A An irregular rhythm is not a normal finding. The pulsation between each beat should be the same or regular.
B A Doppler is not indicated in this case; it is used when the pulse cannot be palpated.
C When an irregular pulse is palpated, the nurse counts the number of pulsations for a full minute.
D Counting the radial pulse again for 15 seconds and multiplying by 4 may reconfirm the initial findings, but does not provide additional data for the nurse on this patient.

8. A nurse is taking vital signs of an adult patient whose oxygen saturation is 96%. The patients temperature is 102 F, blood pressure is 130/86, pulse is 100 beats/min, and respiratory rate is 26 breaths/min. Which factor may be contributing to the elevated respiratory rate?
a. The patients temperature
b. The patients oxygen saturation
c. The patients pulse rate
d. The patients blood pressure
ANS: A

Feedback
A Fever is a factor that may increase respiratory rate, and this patients temperature is 102 F.
B The patients oxygen saturation is a measure of the oxygen carried by hemoglobin and it is within expected limitsabove 90%.
C The patients pulse rate may be due to the high temperature, but a pulse of 100 does not contribute to an elevated respiratory rate in this case.
D The patients blood pressure is higher than normal, but does not contribute to an elevated respiratory rate in this case.

9. Nurses understand that a patients diastolic pressure represents which physiologic function?
a. The pressure needed to open the aortic and pulmonic valves
b. The pressure in blood vessels when the ventricles contract
c. The pressure of the blood returning to the heart from the venous system
d. The pressure in blood vessels when the ventricles are relaxed
ANS: D

Feedback
A The pressure needed to open the aortic and pulmonic valves is called the afterload.
B The pressure in blood vessels when the ventricles contract is the definition of the systolic pressure.
C The pressure of the blood returning to the heart from the venous system is incorrect.
D The pressure in blood vessels when the ventricles are relaxed is the definition of the diastolic pressure.

10. According to research findings, which site is preferred for measuring blood pressure when the nurse is unable to use the patients upper arms?
a. Ankle
b. Thigh
c. Calf
d. Wrist
ANS: A

Feedback
A A study comparing accuracy among sites recommended the ankle as an alternative site for blood pressure measurement.
B The thigh is an alternative site, but the ankle is the preferred site.
C A study comparing accuracy among sites recommended the ankle site in preference to the calf as an alternative site for blood pressure measurement if the upper arm is unavailable.
D Approaches to measuring blood pressure using the wrist and finger sites have been developed, but these lack acceptable accuracy and cost efficiency to be recommended for clinical practice.

12. A nurse notices that the patient has gained 11 lb. If this increase in weight is related to fluid retention, the patient is retaining approximately how many liters of fluid?
a. 1 L
b. 5 L
c. 11 L
d. 24 L
ANS: B

1. Which method of temperature measurement indirectly reflects inner core temperature?
Select all that apply.
a. Axillary temperature
b. Oral temperature
c. Tympanic temperature
d. Rectal temperature
e. Temporal artery temperature
ANS: B, E
Correct: Inner core temperature is measured indirectly because the probe is placed near an artery. For oral temperature, the probe is placed near the carotid artery and the temporal artery is used for the temporal artery temperature.
Incorrect: For axillary, tympanic, and rectal temperatures, the probe is not placed close to any major blood vessels.

3. Which action by the nurse results in the patients blood pressure measurement being falsely high? Select all that apply.
a. Using a blood pressure cuff that is too narrow for the patients upper arm
b. Deflating the blood pressure cuff too rapidly
c. Wrapping the blood pressure cuff too loosely
d. Reinflating the blood pressure cuff before it completely deflates
e. Positioning the patients arm above the level of the heart
ANS: A, C, D, E
Correct: Using a blood pressure cuff that is too narrow for the patients upper arm, wrapping the cuff too loosely, reinflating the cuff before it completely deflates, and positioning the patients arm above the level of the heart all result in readings that are falsely high.
Incorrect: Deflating the blood pressure cuff too rapidly causes the blood pressure reading to be falsely low.

4. Which action by the nurse results in the patients blood pressure measurement being falsely low? Select all that apply.
a. Using a blood pressure cuff that is too wide for the patients arm
b. Not inflating the blood pressure cuff enough
c. Positioning the patients arm above the level of the heart
d. Wrapping the cuff too loosely around the arm
e. Deflating the cuff too rapidly
ANS: A, B, E
Correct: Using a blood pressure cuff that is too wide for the patients arm, not inflating the blood pressure cuff enough, and deflating the cuff too rapidly could result in a false low reading.
Incorrect: Positioning the patients arm above the level of the heart and wrapping the cuff too loosely around the arm causes the blood pressure to be falsely high.

5. The nurse taking a patients blood pressure recognizes that several factors may cause an increased blood pressure reading. Which factors below can increase blood pressure? Select all that apply.
a. The patient rates pain at a level of 7 on a scale of 0 to 10.
b. The cuff was reinflated before being completely deflated.
c. The patient drank cold milk just before the reading.
d. The time of day is late afternoon.
e. The cuff is too wide for the extremity.
ANS: A, B, D
Correct: Rating pain at a level of 7 on a scale of 0 to 10, reinflating the cuff before being completely deflated, and taking the reading in late afternoon are all factors that can increase blood pressure.
Incorrect: Drinking cold milk just before the reading will not affect blood pressure, but drinking caffeine such as coffee or cola may increase blood pressure. A wide cuff makes the reading lower than it actually is rather than higher.
